IMPROVEMENT IN FIREQPLACE GRATES.

Specification forming part of Letters Patent No. 107,483, datedSeptember 20, 1870.

To all whom it may concern Beit known that I, JOSEPH HACKETT, ofLouisville, in the county of Jefferson and State of Kentucky, haveinvented a new and Improved Fire-Grate and Tile; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to make and use the same. n

Figure l represents a front view of my improved grate. Fig. 2 is avertical transverse section of the same, taken on the plane of the linea: x, Fig. l. Fig. 3 is a horizontal section of the same, taken on theplane of the line y y, Fig. l.

Similar letters ot' reference indicate correspondin g parts.

This invention relates to certain improvements in the construction ofbasket-grates, made in sections, to be readily taken apart and puttogether, as hereinafter more fully described.

My improved basket-grate is made of three pieces, A, B, and C. The backpiece, A, which constitutes also the ends of the grate, is made of ovalform, and has horizontal bars a a, braced by vertical bars b b, in whichform it is easily cast.

The bottom piece, B, is made of concave transverse bars c c, that are atthe ends secured to longitudinal bars d d.

The front piece, O, is constructed of two upright bars, c e, which areconnected by the bows j'.

The bottom piece, B, rests with its ends upon lugs g, that project fromthe frame D of the grate. The back piece, A, rests on the ends of thebottom piece, which has notches for its reception. The uprights of thefront piece enter with their lower ends grooves provided for theirreception in the bottom piece, B.

At the upper end the front piece, C, has proT jecting hooks h h, whichcatch over and lock into the upper part of the back piece, A, as isclearly shown in Fig. 2. The front piece, O, serves thus to actuallylock the grate together and to the frame D.

rIhe smoke plate or tile E is cast or constructed of clay, so as toconstitute a dome over the nre-chamber. It is concave 0n the front andlower face and convex on the opposite side, and has an upward andbackward projecting iiange, e', at its rounded upper edge for guidingthe smoke into the flue. The tile rests upon the hollow back F of thegrate, and has or may have tenons projecting into. the same, to bethereby iirmly secured.

The back frame or lining F of the grate is made hollow, to form an airand combustion chamber. Its front face is perforated at the upper partto discharge the heated air into the products of combustion.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A basket grate composed of three pieces,

A, B, and O, substantially as herein shown and described.

2. The front piece, C, of a sectional basket grate, provided withvertical pieces c and hooks h, for the purpose of locking the entiregrate together, substantially as herein shown and described.
